Trigger the standard autoloader as the last resort

[sanmai]

As v2 isn't here yet, and looking at #232 it is unclear if it will be coming anytime soon, and as we have to put up with annoying deprecated functions, here I propose to fall back to the standard autoloader if nothing else worked, and if there's no custom loader defined.

Fixes #270

I intentionally did not add any tests as this is a PoC. Please tell me if this makes any sence, and then I'll make a try with tests.

[stof]

shouldn't it check for both $loaders and $autoloadNamespaces if it want to check that nothing was registered explicitly ?

[sanmai]

@stof fair, please see if it is any better now

[stof]

👍 for this, as it means that not registering anything anymore will produce the behavior available in doctrine/annotations 2 (but without forcing anything on existing projects until they remove their explicit registration)

[stof]

there is actually still 1 case changing the behavior for existing projects: when only registerFile was used.

[sanmai]

Well, we can toggle a flag when registerFile is used, then proceeding as we do for other methods, but shall we?

[sanmai]

Isn't you pre-load a class when you use AnnotationRegistry::registerFile? E.g. if you have a class loaded this way, then autoloading won't even trigger. Is there something else I miss here?

[stof]

Well, if you used registerFile, we might still try to discover a different annotation.

@sanmai I've rebased this against the new master after making some changes to our branches. Do you still want to work on this patch? If we can get registerFile behaviour sorted out properly, we can include this in the 1.9 release.

[sanmai]

Yes, I will at least try to remember what's going on here.

[sanmai]

@alcaeus please let me know if this is a passable workaround

[alcaeus]

@sanmai this looks good. I've added a couple of tests and updated the deprecation messages. Pending an approval by @stof this is ready for 1.9. Thank you very much for this improvement!

[stof]

self::$registerFileUsed must be reset to false when resetting the registry to me.

[sanmai]

@stof done

[alcaeus]

Thanks @sanmai!

[sanmai]

Thank you @stof and @alcaeus!

[sanmai]

It seems like this PR didn't get into 1.9, even though mentioned in the changelog.

Please confirm.

[sanmai]

All clear. Thank you.
